Dear Anyuta! I am sending corrections to the proofs I received today. I have received:
(.) pp. 97-112 typeset.
(.) galleys 81-97 (pp. 302-364 of the manuscript) not yet typeset.

* I. I. Skvortsov-Stepanov, who rendered the closest assistance in the publication of the book "Materialism and Empirio-Criticism." — Ed.

But between these two there is a gap: the typeset portion ends at p. 274 of the manuscript (there are still pp. 274a, 274d), while the galleys begin at p. 302. Consequently, approximately 27 pages of the manuscript are missing!! Has an entire typeset sheet not been lost? Did it fall out of the wrapper? Or perhaps it was accidentally forgotten to be sent or issued from the printing office? I most earnestly request that you send me the proofs of these missing pages (p. 274 - p. 302 of the manuscript) and in any case take measures to ensure that they cannot be omitted during typesetting and printing. The missing portion turned out to be especially important for me and for my book.

Here is a more precise description of the gap, according to the manuscript. The last words of the typeset 112th page are: "These active forces should." In the manuscript this will be p. 274, or 274a, or 274b. After these words the gap begins. Pages 274a - 302 are missing, up to and including the words: "yet another quotation from Bazarov," that is, up to and including the 3rd line from the top. Here is the exact extent of the gap264.

There is one more error, or rather, not an error, but something capable of causing an error during typesetting—in the galleys: on galley 88, seventeen lines from the bottom, beginning with the words: "gelem" (p. 14 of the fourth German edition) and so on, p. 338 of the manuscript should be placed at the end of galley 89.

In other words: in the typesetting, after the words: "religious experience" (line 18 from the bottom on galley 88, line 6 from the top, p. 334 of the manuscript) come the words: "gelem" (p. 14 and so on), that is, p. 338, line 7 from the top. One must look carefully to ensure that no error occurs during typesetting.

I urgently request that the final proofreading (and correspondence with me) be entrusted for payment to someone who knows languages. Let Mitya take one hundred rubles, go to the "writer" and hire either him or a person recommended by him to do the final reading of proofs and correspondence with me. This is necessary to do, because clearly you have no time for proofs now, and you will only be tormented and distressed. I urgently request that you do this immediately.

Yesterday I wrote to you and Manyasha wrote as well. I embrace mama warmly. "Un peu mieux" — that is very indefinite...265 Write.

I press your hand firmly. Your V. U.

P.S. Please also send me the already printed sheets immediately: I shall compile a list of misprints. This is very important, because some things will be possible to correct even after the entire book is printed.
